Title: Drilling method of injection molding and drilling device therefor
Inventor: NAKANO HAJIME
IPC: B29C45/00
Filed: 1987-02-13
Abstract: PURPOSE:To prevent generation of weld line, burn marks or internal stress in a molding by a method in which the tip of a punch projects and penetrates thermoplastic resin, and after solidification by cooling, the punch is retracted, whereby the molding is drilled. CONSTITUTION:The air gap 5 of the shape of a hemisphere-shell is formed corresponding to a product by the recessed portion 3 and the projected portion 4 of top and bottom forces 1, 2. The thermoplastic resin melted by heating is injected into the mold from a nozzle, and the air gap 5 is filled with the thermoplastic resin by way of the sprue 7 and a gate 6 provided in the connecting part of the top force 1 to the bottom force 2. Then the tip 9a of a punch 9 is projected in the air gap 5 by operating a punch driving mechanism, and its tip is contacted with the tip of a pin 11, and then the punch 9 penetrates the thermoplastic resin in the molten state in the thick wall direction thereof. The thermoplastic resin is cooled and solidified, while keeping the penetrated state by the punch 9. After the thermoplastic resin in the air gap 5 has been solidified, the tip 9a of the punch 9 is retracted in the top force 1 by operating the punch driving mechanism. Then the mold is opened and the molding is taken out.

Abstract: PURPOSE:To obtain a magnetic head core having a high accuracy through a simple method, by sticking a nonmagnetic material to the groove part and the gap forming surface formed at the end part of a magnetic block substance and then polishing the nonmagnetic material on the gap forming surface into a prescribed size. CONSTITUTION:The groove part 1b is formed at the front and back parts of a rectangular parallelepiped block substance 1 of the ferrite or the like excepting the gap forming surface 1a having a prescribed gap length (l). Then the nonmagnetic material 2 is put into the groove part 1b to be heated up to the melting point of the material 2, and thus both the part 1b and the gap forming surface 1a are filled with the material 2. Thereafter, the material 2 is polished until it is turned into a plane mirror surface and so that a prescribed gap length (t) is secured for the material 2 on the surface 1a. A part of the block substance 1 is cut to obtain a magnetic head core 3. Such core 3 has a higher gap accuracy than the conventional magnetic head that uses a gap spacer such as a gap plate or the like.

SOLUTION: To a hot water supply system 2 is connected a small water heater by means of a hot water supply pipe 3, water heated therein is discharged from a faucet 6 through an outlet pipe 5. To the faucet 6 is connected a water supply pipe 7 connected with a water pipe 8, water from the outlet pipe 5 and water from the water supply pipe 7 are mixed and discharged by the faucet 6. The water supply pipe 7 is connected to the hot water supply system 2, and water from the water pipe 8 is supplied into the hot water supply system 2. Since a heat loss results when the small water heater 4 is heated always, the small water heater 4 is so controlled as to operate only when a switch of the hot water supply system 2 is on.  Hot water from the small water heater 4 is supplied to the faucet 6 before the hot water is supplied from the hot water supply system 2 to the faucet 6, thereby to reduce a hot water waiting time when the faucet 6 is opened.

Title: Combustion device of liquid fuel
Inventor: KONAKAWA KATSUZOU
IPC: F23D11/40
Filed: 1984-02-21
Abstract: PURPOSE:To eliminate the development of unburnt gas even when ambient temperature rises by a structure wherein a fuel capillary equipped with a nozzle at its tip is made of material having large thermal expansion coefficient. CONSTITUTION:A pipe having the thermal expansion coefficient of about 1X10<-4> or above such as polyester, polyethylene, paraffin or the like is employed as a constitutional material of a fuel capillary equipped with a nozzle at its tip. Both the temperatures of the fuel capillary 6 and of the fuel in the capillary 6 are kept during steady combustion at temperatures as low as 40-60 deg.C while receiving the temperature of a vaporizer 1 by means of the cooling effect of inflowing combustion air and the sensible heat of fuel. When the supply of fuel is stopped instantly for extinguishing, heat flows towards the capillary 6 side. Consequently, the volumes of the capillary 6 and of fuel expand. Because the thermal expansion coefficient of the capillary is about 1X10<-4> while the expansion coefficient of fuel is 1.1X10<-3>, the amounts of volumetric expansion of both the capillary and fuel equal to each other, resulting in causing no pushing-out of fuel from the fuel capillary 6 to the vaporizer 1 and consequently no production of odor due to the development of unburnt fuel.
